OF THE DISSERTATION xv CHAPTER 1. Ultra-wideband Communication Overview 1 1.
Recent advances in wideband impulse technology, low power communication along with unlicensed band have enabled ultra wide band (UWB) as a leading technology for future wireless applications. This paper outlines the applications of emerging UWB technology in a private and commercial sector. We further talk about UWB technology for a wireless body area network (WBAN).
BACKGROUND In this animal study, we evaluated a modified pancreas perfusion method to improve the quality of harvested pancreas in rats. In this model, the portal vein was used as the outflow route during the pancreas perfusion. METHODS Forty-eight male Wistar rats were randomly divided into study group and control group, with 24 rats in each group. In the study group, the portal vein was use...
a novel ultra-high compliance, low power, very accurate and high output impedance current output stage (cos) with extremely high output current drive capability is proposed in this paper. the principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by hspice simulation in tsmc 0.18µm cmos, bsim3, and level4...
Under the condition of super-shallow coverage and small spacing, tunnel construction is easy to cause large structural deformation. The mechanical properties supporting effect with spacing are summarized. Finite element software used simulate on group by changing distance. results show that increase distance, settlement value middle has a smaller distribution law, when distance exceeds 3 m, max...
